10 Monkey D. Luffy Is Well Known For His Lack Of Intelligence And Recklessness

As the main protagonist in One Piece, it’s to be expected that Luffy is one of the most popular characters. However, One Piece wouldn’t be as popular as it is if Luffy wasn't as likable as he is. With his lack of intelligence and his foolish bravery, Luffy gets into more trouble than most pirates.

But it’s his love for his friends and his fellow pirates that make him so likable. He will do anything for them, and will protect them when they're hurt, no matter the cost.

9 Roronoa Zoro Is Reserved, Funny, And Always Lost

Even though Zoro is a reserved guy, it's his comedic nature and his complete lack of direction as a pirate that draws people to him. He is also highly logical and whenever there’s a situation that needs logic, it’s him who the crew turns to for advice.

Zoro also has a never-give-up attitude that many find endearing. He won’t stop until he’s achieved his goal or defeated his opponent. If that doesn’t happen, like in the Baratie Arc against Mihawk, he’s still praised for his determination and strength.

8 Nami May Not Be The Bravest, But She's Smart And Bold

With a dark and horrible past, Nami is favorited by many for her strength and strong-willed personality. In the beginning, she hated pirates, but after getting to know Luffy, she came to the realization that not all pirates are bad.

She may not be viewed as brave, but her strength lies in her knowledge of the world and the evil that dwells within it. She’s compassionate, funny, and always sticks up for her crew.

7 Sanji Is Cool And Calm In Any Situation

Thanks to his background as an actual prince before renouncing his title and his family, Sanji is cool, calm, and collected. He speaks eloquently, which is unusual for a pirate, and often reminds people of a spy—which is one of the reasons why he’s so popular.

He's a comedic character, constantly making a fool of himself in front of beautiful women or when he’s angry with one of his crewmates. Sanji is also compassionate, chivalrous, brave, and loyal, all of which are traits that make him liked by both his crewmates and viewers alike.

6 Shanks Has A Strong Moral Compass And Fights For What's Right

As the pirate who Luffy admired and wanted to surpass, Shanks is one incredibly impressive man. With his charismatic and laid-back attitude, he and his crew are often found drinking alcohol and having a good time. Deep down, however, Shanks has a deep-rooted moral compass and tends to avoid conflict, preferring to create peace through diplomatic means.

Shanks is so popular and well-liked because his carefree attitude ends when his friends are hurt or in danger. In these situations, he becomes a man both respected and feared.

5 Nico Robin Has A Morbid Sense Of Humor And Is Loyal To Luffy

Robin is one of the few members of the Straw Hats who will follow Luffy without question. She’s intelligent and knowledgeable and is often sought after for her advice. She may be quiet, but she has an unexpected side to her that makes her even more likable.

Robin can be macabre, and she likes to point out gross or disgusting facts, often speculating how members of her crew will meet their end in as much gruesome detail as possible. But she does it in a way that’s comedic and enjoyable—for viewers, at least.

4 Boa Hancock Is Beautiful, Deadly, And Caring All In One

As beautiful as she is deadly, Boa Hancock is certainly a likable character. She’s strong not only in mind but in strength and spirit, and she has no problem using her feminine wiles to make people forgive her. Boa is also ruthless, cunning, and stubborn to a fault. No matter how many times Luffy turns down her marriage proposals, she becomes more determined than ever to make him her husband.

It’s only when her dark past is revealed that viewers understand why she is the way she is, and why she fears growing close to people and showing her soft and caring side.

3 Silvers Rayleigh Is A Retired Pirate Who Goes Where The Sea Takes Him

Lighthearted, funny, and a man who goes where the tides take him, Silvers Rayleigh is a knowledgeable, strong-willed retired pirate who is well-loved by the characters in One Piece, as well as by viewers. He’s the type of man who plans, preferring not to jump into things headfirst.

His friendship with Luffy is as heartbreaking as it is heartwarming, as Luffy reminds Rayleigh of his previous captain. During the time skip, the two bonded as Rayleigh taught Luffy and helped develop him into the character he is today.

2 Carrot Has A Child-Like Sense Of Wonder And She Cares For Her Friends Dearly

Carrot is the type of character who can go from sweet and naïve to downright angry in a heartbeat—especially if someone steals her carrots. She’s well-liked not only for her comedic personality but also because of her fierce loyalty and love for her friends. She’d do just about anything for them.

Even though she’s a warrior, her childlike wonder, adventurous spirit, and fear of ghosts make her endearing. She’s smart and cunning, too, often creating plans in a matter of moments. She’s a truly valuable ally to the Straw Hat Pirates.

1 Portgas D. Ace Is Well-Mannered And Always Falling Asleep

Unlike his brother Luffy, Ace is extremely well-mannered and intelligent, making him both more likable and more tolerable. But he wasn’t always that way. He too, has an empty pit for a stomach, loves to party and have fun, and is just as reckless as Luffy and even more impulsive. Even though they weren't blood-related, they were still quite close.

One of Ace's most endearing traits is his narcolepsy—his ability to fall asleep just about anywhere and while doing anything. This led to some pretty comedic situations, which makes him all the more lovable.
